Executive device accounts for about the 80% of pneumatic system power executing device.In the case, section of the energy conservation of cylinder for pneumatic system
It can be particularly important.
Summary of the invention
In view of the above problems, the present invention provides the rows that a kind of novel cylinder exhaust overbottom pressure reduces cylinder using system
Gas loss, improves the energy utilization efficiency of compressed air.The novel cylinder exhaust overbottom pressure of one kind of the invention is main using system
Including compressed air energy source, pressure reducing valve, two-bit triplet solenoid valve, check valve, gas tank, cylinder and between connecting line.
Specific cylinder overbottom pressure is as follows using system work process: compressed air is gone out by compressed air energy source stream, is depressurized through pressure reducing valve
Pressed gas later is flowed into cylinder by solenoid valve 7, and under the driving of compressed air, piston is run to the right, common cylinder
For drive system in order to guarantee speed that piston rod is run to the right, it is outer to cause energy that the gas of rod chamber can be expelled directly out cylinder
Loss.In the present system, system detection cylinder rod chamber gas pressure, when cylinder rod chamber gas pressure is higher than gas in gas tank 14
When body pressure, rod chamber gas flows into gas tank 14 by solenoid valve 11, solenoid valve 12 and check valve 13.When cylinder rod chamber gas
When body pressure is less than 14 gas pressure of gas tank, gas is directly excluded outside cylinder by solenoid valve 11, solenoid valve 12 in rod chamber, from
And achieve the purpose that be vented hydraulic recovery.Equally, when the course of work needs cylinder rod to retract, gone out by compressed air energy source stream
Compressed air flows into cylinder rod chamber via pressure reducing valve, two-bit triplet solenoid valve 11, so that piston is driven to run to the left, system inspection
Gas pressure in rodless cavity is surveyed, when gas pressure is higher than gas pressure in gas tank 5 in rodless cavity, rodless cavity gas passes through electromagnetism
Valve 7, solenoid valve 3 and check valve 4 flow into gas tank 5.When rodless cavity pressure is less than 5 pressure of gas tank, gas passes through in rodless cavity
Solenoid valve 7, solenoid valve 3 directly exclude outside cylinder, to achieve the purpose that be vented hydraulic recovery.Gas recovery can be used as other
The driving gas of equipment.Beneficial effects of the present invention: the commutation and detection cylinder intracavity gas pressure that the present invention passes through solenoid valve
Power gentle pressure tank getter cylinder pressure at expulsion back and forth, improves the energy utilization efficiency of cylinder.
